Students’ engagement with their group in a problem‐based learning curriculum

Abstract

In a new enquiry-based learning dental curriculum, problem-based learning (PBL) was chosen as a central methodology because it promotes a collaborative and constructive approach to learning. However, inevitably, some groups function worse than others. This study explores the relationship between group functionality and individuals' results on knowledge-based assessment. It also sought to establish whether using the Belbin team role theory could improve group functionality. Students completed the Belbin team role inventory that assigns individuals to a team role type and were allocated to either an ideal Belbin group or a control group. To evaluate the functionality of the groups, Macgowan's group engagement measure was completed after 18 and 31 weeks for each student by their group facilitator. The scores were summed and averaged giving a group engagement score for each group. Relationships between group engagement, individual performance in assessment in weeks 18 and 31 and Belbin and non-Belbin teams were investigated. Individual group engagement scores and performance in the knowledge tests had a statistically significant positive relationship despite the small number of students involved (62). However, no correlation was shown between Belbin groups and group engagement scores. Those students who engaged most with the PBL process performed markedly better in assessments of knowledge. Using Belbin's team role theory to place students in PBL groups in an effort to increase group functionality had no effect when compared with non-Belbin control groups.
